NH3 is a stronger acid than ROH (as electronegativity of N<O .. so it will hold the H atom less firmly )

=> the conjugate base NH2- is weaker than RO-

but there is a +I effect from R group, so -ve charge on O will become unstable, so don't you think that it will be more basic.......

Sky, the conjugate base RO- is less stable than NH2- due to +I effect from R...
but does that necessarily mean that RO- is stronger???

but i told about strength of acid...

Don't say that R is tert methyl or so... :P then it is NH2-

oh i am WRONG!

NH2- is a stronger base than RO- .... (saw in arihant today.. ;) :P)

NH3 is a weker acid than ROH... coz N is less electronegative than O...

dinitromethane? bcos of presence of two electron withdrawing groups?

better explanation. please

Anirudh Narayanan ·

But ans is correct?

Anirudh Narayanan ·

Two NO2 groups make the carbon more postive. So it's easier to remove a H+. In CH3COOH, only one C=O group. So effect is less pronounced?

IGNORE EXPLAINATION IF IT SOUNDS STUUUUPID [1]

NH2- is the more basic because the conjugate acid of NH2- is weaker than that of the RO-
